BALL-BEARING.

SPECIFICATION forming part of Letters Patent No. 754,436, dated March 15, 1904.

Application filed December 19, 1902. Serial No. 135,912. (No model.)

To all whom it may concern;

- Be it known that I, TYRRELDHUBERT DUN- GOMBE, chemist, of the city of St. Thomas, in the county of Elgin, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Ball-Bearings; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to an improved ballbearing in which the balls are carried in a solid ring mounted on the shaft and each ball being carried in a separate opening, thus doing away with the circumferential ball-race, in which there is considerable binding and friction. The halls are so arranged in the bearing that any ball can be removed or replaced without interfering with the other balls. I attain these objects by the illustrations in the accompanying drawings, in which Figure 1 is a perspective View of the hearing partially broken away to show the balls. Fig. 2 is a perspective view of the retainingring. Fig. 3 is alongitudinal section on lines I) I), Fig. 4. Fig. L-is a cross-sectional view of the bearing. Fig. 5 is a longitudinal View on lines a, a, Fig. 4. Fig. 6 is a perspective Fig. 7 is a view of one of the balls.

Likeletters refer to like parts throughout the specification and drawings.

a is the retaining-ring, through which passes the circular bore 6 to receive the rotatable shaft 0. Passing through the ring a at predetermined intervals are a series of circular openings 6, and connecting each two openings is an oblong passage'd. Carried in each of the circular openings 6 is an antifriction-ball f, andin each of the passages 61 is an antifriction-roller 9. Each roller is in frictional contact with two balls, which are free to revolve together. The ends it of the roller 9 terminate in a point and bear against the inner faces of the ends of the passages CZ, thus obviating considerable friction. Surrounding the ring a is a metal sleeve .c', which retains the balls in the openings. The sleeve 2' may be fastened to the ring a in any suitable manner. periphery of the shaft 0 and the inner face of the sleeve 2'. r

I do not wish to confine myself to any specified number of balls or rollers or to the eX- act shape of the openings in the ring to contain the balls, as I may make slight changes Without deviating from the nature of my invention.

What I claim as new, and desire to secure by Letters Patent, is

1. In a ball-bearing,a retaining-ringformed 'in one piece,'said retaining-ring having a series of openings forming a series of projections, there being passages in said projections between said openings, antifriction-balls in said openings, and antifriction spacing-rollers in said passages, substantially as specified.

2. In a ball-bearing, a retaining-ring formed in one piece, said retaining-ring having a series of circular openings forming a series of projections, there being passages in said pro' jections between said openings, antifrictionballs in said openings, and antifriction spacing-rollers in said passages, the said rollers being in frictional contact with the said balls, a circular sleeve surrounding the said retaining-ring, substantially as specified.
